Abstract: | In this study, we present a new approach to distinguish original honey from sucrose-overdosed one by a colloid of oxygen-deficient TiO2 nanoparticles (NPs). Results show that the original honey does not affect the colloidal NPs while sucrose-overdosed one precipitates it in a few seconds. Our studies show that the precipitating time has a non-linear dependence on absorption peak intensity, and the settling rate increases up to 0.185 cm min?1 by increasing sucrose in honey. Our results show that sucrose in honey can enhance the hydrodynamic radius of NPs up to 482.9 nm by suppressing zeta potential besides agglomerating the NPs and a blue shift in the absorption peak (up to 20 eV). The macroscopic behavior of the honey-solved colloid can be applied to determine the quality of honey according to the settling rate in a few minutes. |
